In the season premiere of "Gossip Girl" this past Monday, Sebastian Stan reemerged as world-class traveling lothario, troublemaker Carter Baizen. Now, with a new season already underway, Hollywood Crush is naming Sebastian this week's Hump Day Hottie. We just hope he'll be sticking around and not saying "XOXO" anytime soon.

Press play on the video below to see more of Sebastian and keep reading for more juicy details about him.

Vital Stats: The 26-year-old was born in Romania and lived in Austria for a while before moving to New York state. He later went to Rutgers University and studied drama at Shakespeare's Globe Theatre in London. And when he's not trying to make Serena fall in love with him on TV, he's busy being in love with Blair, we mean Leighton Meester, in real life.

Where you might have already seen him: He's been in a slew of projects including "Kings," "The Education of Charlie Banks," and "Rachel Getting Married." Most recently he starred as Ashton Kutcher's right hand man in the movie, "Spread."

"We kind of have that Vince Vaughn/ Jon Favreau relationship," he told MTV News about his role in the flick. "We sort of nag each other. We need each other to be in each other's lives."
Why you should take notice of him now: He's back on "Gossip Girl" as Carter. And when he spoke to Hollywood Crush last he promised that you'd be seeing more of him this time around. And, as we all saw in the show's season premiere, he spent a lot of time with Serena globetrotting around Europe and he's not going to give her up that easily. She may be resisting, but we have to admit with his bad boy ways and that pretty face it would be hard for us to stay away.

Until next Wednesday, when we nominate yet another hottie, you can get the rest of your man candy fix by clicking on Sebastian's photo below to see who else is in our backlog of studs!
